# It separates the FastCGI (PHP-FPM) failures from the Nginx failures.
# I have noticed that sometimes fpm.log and php.log do not contain a record
# about PHP fatal errors like «Uncaught Error: Function name must be a string»,
# but the Nginx log contains: «PHP message: PHP Fatal error:  Uncaught Error: Function name must be a string».
# So I decided to use the separate log for such records.
